A preliminary study of apparent diffusion coefficient in chemotherapy-induced liver damage.

Objectives: To investigate changes in the hepatic apparent diffusion coefficient (ADC) in patients undergoing chemotherapy.

Methods: We enrolled 54 patients (25 women; mean age 57.0±13.

Perfusion CT findings in liver of patients with tumor during chemotherapy.

Aim: To investigate the microcirculation changes in liver of patients with tumor during chemotherapy by perfusion computed tomography (CT).

Methods: Sixty patients with tumor and 20 controls were enrolled in this study. Perfusion CT parameters of patients and controls were compared, including hepatic perfusion index (HPI), mean transit time (MTT), and permeability-surface area product (PS).

Diffusion-weighted imaging of prostate cancer: correlation between apparent diffusion coefficient values and tumor proliferation.

Purpose: To investigate whether the apparent diffusion coefficient (ADC) values of prostate cancer (PCa) are able to reflect tumor proliferation.

Materials And Methods: The clinical and pathological information for 38 patients with PCa and 33 patients with benign prostate hyperplasia (BPH) were studied. Examination of the patients was performed using a 1.

1H-MRSI of prostate cancer: the relationship between metabolite ratio and tumor proliferation.

Purpose: To investigate whether 1H-MRSI can be used to predict the proliferative activity of prostate cancer.

Materials And Methods: Thirty-eight patients with prostate cancer (PCa) and thirty-three patients with benign prostate hyperplasia (BPH) were included in this study. Patients were examined in supine position using a 1.

[Copolymer of 2-hydroxyethyl methacrylate for cerebral arteriovenous malformation: an experimental study].

Objective: To investigate the feasibility of using methyl methacrylate (MMA) and 2-hydroxyethyl methacrylate (HEMA) to embolize cerebral arteriovenous malformations (AVM).

Methods: Methyl methacrylate (MMA) and 2-hydroxyethyl methacrylate (HEMA) in the ratio of 9:1 were solved in 16% alcohol so as to make a kind of copolymer (CoHEMA). 12 g glass beads 2 mm in diameter were put into a container so as to construct an in vitro model of AVM.

Technical feasibility and histopathologic studies of poly (N-isopropylacrylamide) as a non-adhesive embolic agent in swine rete mirabile.

Background: Non-adhesive liquid embolic agents are increasingly gaining importance in the embolization of cerebral arteriovenous malformations (AVMs). We investigated the use of poly (N-isopropylacrylamide) (PNIPAM) as a non-adhesive embolic agent in swine rete mirabile.

Methods: The PNIPAM hydrogel was mixed with iohexol and embolization was performed in swine rete mirabile in 30 animals.
